Sure. That's true. Copyright doesn't protect factual data. But there is what's legal, and there is what's ethical. If I traveled around the country, measuring the heights of roller coasters for my website rollercoasterheights.com, I did it to get people to come to my site. If that information is harvested from my site and displayed elsewhere, I've done a lot of work for nothing.
